A series of diagnostic tools is grouped together under the SETUPàMOREàDIAG
menu, as these parameters are dependent on firmware revision (see Appendix A). These
tools can be used in a variety of troubleshooting and diagnostic procedures and are
referred to in many places of the maintenance and trouble-shooting sections of this
manual.
The various operating modes available under the DIAG menu are:
SUBMENU FUNCTION
Allows observation of all digital and analog signals in
the instrument. Allows certain digital signals such as
valves and heaters to be toggled ON and OFF.
When entered, the analyzer performs an analog
output step test. This can be used to calibrate a
chart recorder or to test the analog output accuracy.
This submenu allows the user to configure the
analyzer's analog output channels, including
choosing what parameter will be output on each
channel. Instructions that appear here allow
adjustment and calibration of the voltage signals
associated with each output as well as calibration of
the analog to digital converter circuitry on the
motherboard.
When activated, the analyzer performs an electrical
test, which generates a voltage intended to simulate
the measure and reference outputs of the
SYNC/DEMOD board to verify the signal handling
and conditioning of these signals.
Disconnects the preamp from synchronous
demodulation circuitry on the SYNC/DEMOD PCA to
establish the dark offset values for the measure and
reference channel.
Allows the user to calibrate the sample pressure
sensor.
This function is used to calibrate the gas flow output
signals of sample gas and ozone supply.
Selects one of the available test channel signals to
output over the A4 analog output channel.
